Since the introduction of MRI, the arachnoiditis could easily haute been diagnosed by confirming the abnormal distribution of the roots in the dural sac. But the arachnoiditis-like pattern of nerve root distribution in a degenerative disc disease has been regarded as a an incorrect diagnosis of arachnoiditis. The arachnoiditis has been one of the most serious complication in the failed back surgery syndrome. MR images of 32 patients with acute or chronic radicular pain syndrome were investigated by a radiologist and a orthopedc surgeon. 17 patients had lumbar disc herniation; 13 patients, pure spinal stenosis; 2 patients, spondylolisthesis. The discriminant analysis was used to calculate the cutting point of clumping for the abnormal nerve root distribution and to assess the relationship between the arachnoiditis-like pattern of nerve root distribution and other factors According to the result of calculation, the cutting point of clumping In spinal stenosis was 9mm and that in a disc herniation was 6mm. Central clumping of nerve roots in the durn is considered as a characteristic finding at the constricted level of the lumbar degenerative disease. However, the appearance is not a differentiating factor between the adhesive arachnoiditis and constriction in the lumbar degenerative disease. Clinically, the adhesive arachnoiditis should be suspected in the lumbar degenerative disease with the nerve root clumping at multiple level, not associated with remarkable constriction of spinal canal. In the disc herniation with their sagittal diameter over 6mm, the clumping seems to imply the possibility of association with adhesive arachnoiditis.

Arachnoid cyst of the velum interpositum is unusual and causes symptoms similar to those seen with a third ventricular mass. This report describes a case in which the arachnoid cyst occupied the cistern of the velum interpositum and was coincident with multiple cranial neuropathies. The patient was treated by endoscopic fenestration of the cyst. The surgery resulted in decreased in the size of the cyst but aggravation of cranial neuropathies. The patient underwent methylprednisolone pulse therapy and intravenous immunoglobulin administration under the impression of the multiple cranial neuropathies and recovered completely 3 months later. The authors conclude that combined neurological disease that needs medical treatment should be differentiated and priority of the treatment should be determined carefully if arachnoid cyst is associated with unrelated or ambiguous neurological symptoms and signs. Careful considerations of cause and effect may avoid an unnecessary surgical manipulation

An ELISA was established to measure bovine IgG directed against the recombinant antigenic determinant of Nc-p43, a major surface antigen of Neospora caninum. In a previous study, two thirds of the Cterminal of the molecule was expressed as a 6 x His tagged protein (Ncp43P) for ELISA using 2/3 of the N-terminal of SAG1 from Toxoplasma gondii as a control (TgSAG1A). Among 852 cattle sera collected from stock farms scattered nation-wide, 103 sera (12.1%) were found to react with Ncp43P positively, but no positive reaction was observed with TgSAG1A. This study shows that Ncp43P could be available as an efficient antigen for the diagnosis of neosporosis in cattle. Furthermore, it together with TgSAG1A, could be useful for the differential diagnosis of N. caninum and T. gondii infections in other mammals.

It is well known that the medullary carcinoma of the breast is one of the special types of breast carcinoma with a good prognosis. At present, the medullary carcinoma of the breast is subclassified into 3 types: typical medullary, atypical medullary and nonmedullary carcinoma. Among them, the former has the best prognosis. We reviewed the film mammographic and ultrasonomammographic findings of 13 patients according to the reevaluated histopathologic diagnosis. Typical medullary carcinoma shows a well circumscribed mass with surrounding halo on film mammogram, and well defined mass with central intermediate echogenicity and peripheral low echogenicity and posterior acoustic enhancement on ultrasonomammogram. Atypical medullary carcinoma shows relatively well circumscribed mass with partial marginal obliteration on film mammogram, and irregular bordered mass with inhomogeneous echogenicity due to focal necrosis in the mass and associated findings of thick boundary, asymetrical lateral shadowing on ultrasonomammogram. Nonmedullary carcinoma shows lobulated mass with surrounding parenchymal distortion and skin thickening on film mammogram, and relatively well defined lobulating mass with surrounding parenchymal distortion and marked heterogeneous internal echogenicity on ultrasonomammogram. Therefore, differentiation between typical medullary carcinoma with good prognosis and atypical medulary or nonmedullary carcinoma with poor prognosis, may be possible by various diagnostic imaging modalities preoperatively. But further collective study shall be needed in near future.

The antigenic domain of the major surface protein (Nc-p43) of Neospora caninum was examined by polymerase chain reaction of its gene fragments and recombinant expression as GST fusion proteins. The fragments of Nc-p43 were as follow: a total open reading frame (OFR), T; OFR without signal sequence and C-terminal hydrophobic sequence, S; N-terminal 2/3 parts of S, A; C-terminal 2/3 parts, P; N-terminal 1/3 part, X; middle 1/3 part, Y; and C-terminal 1/3 part, Z, respectively. The DNA fragments were cloned into pGEX-4T vector. Recombinant plasmids transformed into Escherichia coli of BL21 pLysS (DE3) strain were induced to express GST or GST fused fragments of Nc-p43 such as 69 kDa protein for T, 66 kDa for S, 52 kDa for A, 53 kDa for P, and 40 kDa proteins for X, Y, and Z, respectively in SDS-PAGE. The Nc-p43 fragments of T, S, and P reacted with a bovine serum of neosporosis while those of A, X, Y, and Z together with GST did not in the western blot. These findings suggest that the antigenic domain of Nc-p43 of N. caninum may be localized in the C-terminal 2/3 parts. Together with A19 clone in SAG1 of Toxoplasma gondii (Nam et al., 1996), the P fragment of Nc-p43 could be used as efficient antigens to diagnose and differentiate those infections with both species.
